3. Run the engine at normal idle speed for at
least 60 seconds, and leave the engine
running for the rest of this procedure.
4. Fully apply the parking brake, and press the
brake pedal.
5. Place the shift lever momentarily into each
gear position (allowing time for the transmis-
sion to fully engage in each position), ending
with the transmission in PARK.
6. Remove the dipstick, wipe it clean and rein-
sert it until seated.
7. Remove the dipstick again and note the fluid
level on both sides. The fluid level reading is
only valid if there is a solid coating of oil on
both sides of the dipstick. Note that the holes
in the dipstick will be full of fluid if the actual
level is at or above the hole. The fluid level
should be between the “HOT” (upper) refer-
ence holes on the dipstick at normal operat-
ing temperature.If the fluid level is low, add
fluid through the dipstick tube to bring it to
the proper level. Do not overfill. Use ONLY
the specified fluid (see
" Fluids, Lubricants,
and Genuine Parts " for fluid specifications).
After adding any quantity of oil through the
dipstick tube, wait a minimum of two minutes
for the oil to fully drain into the transmission
before rechecking the fluid level.
NOTE:
If it is necessary to check the transmission
below the operating temperature, the fluid
level should be between the two “COLD”
(lower) holes on the dipstick with the fluid at
60-70°F / 16-21°C. Only use the COLD region
of the dipstick as a rough reference when
setting the fluid level after a transmission
service or fluid change. Re-check the fluid
level, and adjust as required, once the trans-
mission reaches normal operating tempera-
ture.
CAUTION!
If the fluid temperature is below 50°F (10°C)
it may not register on the dipstick. Do not add
fluid until the temperature is elevated enough
to produce an accurate reading. Run the
engine at idle, in PARK, to warm the fluid.
8. Reinsert the dipstick. Check for leaks. Re-
lease the parking brake.
NOTE:
To prevent dirt and water from entering the
transmission after checking or replenishing
fluid, make sure that the dipstick cap is
properly reseated. It is normal for the dip-
stick cap to spring back slightly from its
fully seated position, as long as its seal
remains engaged in the dipstick tube.
